Really? I get destroyed by Irelia And a good illaoi when I play top.
But I also don't ever play him top, only adc
It's all about understanding the matchup for the most part, especially against Irelia. You need to keep an eye on your own minions while last hitting and harassing so that you can predict her dash. When one of your minions is low and she's in range to dash at it us either attack move or your blinding dart clicking on the minions position and then you'll attack her the exact instant she becomes untargetable after he dash allowing you to severely punish her for even trying to CS or get near you. Since she's melee you can easily toss a single auto attack her way whenever she walks up to a minion to last hit it as well. It's really important to establish a lead on her before she hits level 6 though otherwise she can wreck you. It's all about positioning and taking advantage of the fact you're better pre-level 6.
As far as Illaoi goes, play it passively and just harras from behind minions, eventually she'll get low and you can all in her with ignite. If she lands her tentacle pull on you then all in her immediately if your strong enough as each attack reduces the duration of the ability and prevents her from proccing it completely. It's important to not let her all in you though either because for the most part this is actually a skill match-up in my opinion. Whoever's better at their champion and/or the lane in general is the one who's most likely to win in this one.
